Using this framework, we then discuss the scopes in relation to appropriate hypothesis-making and an argument about what constitutes a scientifically novel ...
In statistical terms, this belief or assumption is known as a hypothesis. Counterintuitively, what the researcher believes in (or is trying to prove) is called the “alternate” hypothesis, and the opposite is called the “null” hypothesis; every study has a null hypothesis and an alternate hypothesis.

When the research question asks “Does the independent variable affect the dependent variable?”, the null hypothesis (H0) answers “No, there’s no effect in the population.” On the other hand, the alternative hypothesis (HA) answers “Yes, there is an effect in the ...
The null hypothesis is the claim that there’s no effect in the population. If the sample provides enough evidence against the claim that there’s no effect in the population (p ≤ α), then we can reject the null hypothesis. Otherwise, we fail to reject the null hypothesis. Although “fail to reject” may sound awkward, it’s the only wording that statis...
The alternative hypothesis (HA) is the other answer to your research question. It claims that there’s an effect in the population. Often, your alternative hypothesis is the same as your research hypothesis. In other words, it’s the claim that you expect or hope will be true. The alternative hypothesis is the complement to the null hypothesis. Null ...
Null and alternative hypotheses are similar in some ways: 1. They’re both answers to the research question 2. They both make claims about the population 3. They’re both evaluated by statistical tests. However, there are important differences between the two types of hypotheses, summarized in the following table.
To help you write your hypotheses, you can use the template sentences below. If you know which statistical test you’re going to use, you can use the test-specific template sentences. Otherwise, you can use the general template sentences.
